" rel="nofollow - Hi,

This is the first time I've put together a rig. When I turn it on, my screen is blank. The GPU's light up and the CPU fan runs.

Here's my setup:

Board: H81 Pro BTC 2.0

PSU: CORSAIR-HXi-Series-HX1000i

CPU: Intel Celeron Dual-Core G1840

Memory stick: Samsung 32 GB Metal Bar installed with HiveOS

GPUs: 2 x Asus Radeon RX-580

RAM: Kingston HyperX FURY 4GB

Monitor: Raspberry Pi

Speaker: none

Any suggestions?

I'm ambitious! Haha. I connected the Raspberry Pi to the HDMI port on the 1st GPU. I initially got the "Install the PSU's 4-pin connectors on your motherboard." I connected the power supply to both of the 4-pin connectors and the message went away. However, my screen is blank on boot.

I plan on getting a speaker Sunday in case that's needed for diagnosing the problem.

Are all Videocards connected?
Did u try connecting your screen to the Onboard HDMI port?
Did u try a regular screen already and or did u try ur Rasperry Screen on a different PC?

Yes, all those are connected.

When I plug the Raspberry into the onboard HDMI, I get a "no signal" message.

I plugged the Raspberry into a laptop and it worked.

" rel="nofollow - I unplugged everything and plugged it all back in. Now, I'm getting the "no signal" message whether I plug the HDMI cable into the GPU or the onboard HDMI port.

Any ideas?
